Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0023] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] like Figures 1 to 4As shown in the figure, a specific embodiment of this utility model provides an environmentally friendly water-based white glue raw material high-efficiency mixing device, including a stirring mechanism, a driving device and a reaction vessel 1. The reaction vessel 1 is divided into a stirring chamber 2, a water jacket 3 and a supporting shell 4. A vacuum pipe joint 5 and a feed pipe joint 6 are fixedly installed on the upper end of the reaction vessel 1, a liquid outlet pipe joint 7 is fixedly installed on the side wall of the reaction vessel 1, and a discharge pipe joint 8 and a water inlet pipe joint 9 are fixedly installed on the lower end of the reaction vessel 1.

[0025] The stirring mechanism includes a scraper stirring frame 10, which is rotatably disposed at the opening of the rotating shaft of the reactor 1. A spiral stirring frame 11 is rotatably disposed at the through hole of the scraper stirring frame 10. A drive shaft 12 is rotatably disposed at the through hole of the spiral stirring frame 11. A stirring fan 13 is fixedly disposed at the lower end of the drive shaft 12. A support frame 14 is fixedly disposed at the lower end of the stirring chamber 2. The stirring fan 13 is located inside the support frame 14.

[0026] The drive unit includes a motor bracket 15, on which a variable frequency motor 16 is fixedly mounted. A first drive gear 17 and a second drive gear 18 are fixedly mounted sequentially from the inside out on the motor shaft of the variable frequency motor 16. The second drive gear 18 is engaged with a transmission gear set. A first rotating gear 19 is fixedly mounted on the upper shaft of the scraper stirring frame 10. A second rotating gear 20 is fixedly mounted on the upper shaft of the spiral stirring frame 11. A third rotating gear 21 is fixedly mounted on the upper end of the drive shaft 12. The third rotating gear 21 is engaged with the transmission gear set, the first rotating gear 19 is engaged with the transmission gear set, and the second rotating gear 20 is engaged with the first drive gear 17.

[0027] By adopting the above technical solution, this utility model sets up a multi-stage stirring mechanism. The scraper stirring frame 10 can remove the residue on the inner wall of the stirring chamber 2 inside the reactor 1, preventing it from sticking to the inner wall of the stirring chamber 2 during stirring. The stirring fan 13 draws up the raw material deposited at the bottom and disperses it from the support frame 14. Then, the spiral stirring frame 11 stirs it, further enhancing the stirring effect and effectively improving the mixing efficiency and uniformity of the water-based white glue raw material. At the same time, the setting of the variable frequency motor 16 allows the stirring speed to be flexibly adjusted according to actual needs, thereby adapting to the mixing requirements of raw materials with different viscosities. The temperature of the stirring chamber 2 inside the reactor 1 is controlled by the water jacket 3 to ensure that the mixing process is carried out under suitable conditions, further improving the quality stability of the product. Since the scraper stirring frame 10 and the stirring fan 13 rotate in opposite directions to the spiral stirring frame 11, the motor reverses after stirring is completed, which helps to speed up the discharge rate. Moreover, the rotation of the scraper stirring frame 10 facilitates the cleaning of the inner wall of the stirring chamber 2 during discharge.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, the transmission gear set includes a transmission shaft 22, which is rotatably mounted in the transmission shaft fixing groove at the upper end of the reactor 1. From bottom to top, the transmission shaft 22 is fixedly equipped with a first transmission gear 23, a second transmission gear 24, and a third transmission gear 25. The first transmission gear 23 meshes with the first rotating gear 19, the third transmission gear 25 meshes with the third rotating gear 21, and the second transmission gear 24 meshes with the second driving gear 18.

[0029] By adopting the above technical solution, the cooperation between the first transmission gear 23 and the first rotating gear 19 ensures the stable operation of the scraper stirring frame 10 and effectively removes the residue on the inner wall of the stirring chamber 2. The cooperation between the third transmission gear 25 and the third rotating gear 21 ensures the normal operation of the drive shaft 12 driving the stirring fan 13, thereby pumping the raw materials deposited at the bottom to the support frame 14 for dispersion. The cooperation between the second transmission gear 24 and the second drive gear 18 changes the power transmission efficiency, making the entire stirring system run more smoothly and steadily.

[0030] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, fixed lifting rings 26 are fixedly installed on both sides of the upper middle part of the reactor 1.

[0031] By adopting the above technical solution, the setting of the fixed lifting ring 26 facilitates the installation, disassembly and maintenance of the reactor 1, and enhances the convenience and safety of the equipment in practical applications.

[0032] Specifically, such as Figure 3 As shown, the side wall of the support frame 14 has openings with a diameter of 10~20mm.

[0033] By adopting the above technical solution, the openings on the side wall of the support frame 14 are beneficial to promoting the uniform dispersion of raw materials during the stirring process and avoiding uneven mixing due to local accumulation.

[0034] Specifically, such as Figure 2 and Figure 4 As shown, the spiral stirring frame 11 consists of a spiral stirring shaft 27, an arc-shaped stirring blade 28, and a connecting rod 29.

[0035] By adopting the above technical solution, the spiral stirring shaft 27 generates an upward thrust through continuous rotation, which continuously transports the raw materials at the bottom upward, thereby forming a circulating flow effect. The arc-shaped stirring blade 28 can effectively stir the raw materials and form vortices during the stirring process, so that the contact between different components is more sufficient, further improving the uniformity of mixing. The connecting rod 29 is used to fix the arc-shaped stirring blade 28 and the spiral stirring shaft 27, providing fixed support for the arc-shaped stirring blade 28.

[0036] Specifically, such as Figure 2 As shown, a degassing membrane 30 is provided at the connection between the vacuum pipe joint 5 and the stirring chamber 2.

[0037] By adopting the above technical solution, the degassing membrane 30 can effectively remove the air bubbles generated during the stirring process and avoid the impact of air bubbles on the uniformity of raw material mixing.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
